This is a real shame. I had hoped that this story was false but it appears that Nico Dauphiné, former researcher at the Smithsonian National Zoo's Migratory Bird Center has been found guilty of misdemeanor attempted cruelty to animals for sprinkling poison atop cat food intended for feral cats living in Washington, D.C. This does nothing to reach some sort of reasonable understanding with the misguided yet well intentioned cat lobbyists. Non native cats living in feral colonies is habitat destruction by humans. Cats living in the environment are the same as birds hitting windows or someone bulldozing nesting and feeding habitat.
